Calgary can be grown in large outdoor containers as a sophisticated decoration, or in the ground as a hard-working landscape shrub. They’ll easily manage freezing cold temperatures, along with high heat and humidity.

Use them in a series of large exterior containers to effortlessly amp up the style of your patio. Try a pair of containers flanking either side of your front door.

You’ll never grow tired of these pretty “Thrillers”. Each year, add annuals around the base of your container-grown Boxwood to vary the look from season to season.

Try your hand at the ancient art of topiary. Sculpt specimen plants into decorative shapes, from fanciful to formal.

For a wonderfully high-end look, fill garden beds with a series of Boxwood in a geometric planting pattern. Or, create a low hedge to define your space.

Plant them 20 inches apart on center, measuring from the center of one to the center of the next. The plants will grow together and create a solid screen.

These are classic foundation shrubs that show off your home’s architecture with ease. Clip and shear them into a formal hedge after flowering. Many people are choosing to allow them to grow into a soft, fluffy, natural shape.

Tips for Care

Calgary Boxwood performs best in full sun or partial shade with at least four hours of direct sunlight. Provide well-drained soil, or improve drainage with a raised planting bed or container.

Apply a thick, three-inch layer of mulch over the root system to keep it nice and cool. You’ll want to ensure the mulch isn’t touching the main stems. Pull it back by several inches to maintain good air circulation.

Apply a moderate amount of water on a regular basis to supplement rainfall. Ensure that your plants receive adequate water in late fall. Moisture in their leaves will protect your evergreens against drying winter winds.

In early spring, apply an organic, slow-release fertilizer according to the label directions. Prune to shape after flowering in early summer.

There is nothing as handsome as a lush Calgary Boxwood. These compact green ovals can become the mainstay of your landscaping.
